In 881, three years after the death of Rhodri at the hands of the English, his son Anarawd confronted the Mercians at Conwy.

In 878, Rhodri Mawr was slain by the English along with his son Gwriad. The Annales Cambriae notes their deaths at the hands of “the Saxons”, although it does not specify the location. Documented: Annales Cambriae, death entry labelled 877 in the linked translation; dated 878 by J. E. Lloyd Historian J. E. Lloyd attributes Rhodri’s death to the Mercians. Documented: J. E. Lloyd, Dictionary of Welsh Biography, “Anarawd ap Rhodri”
How Did the Battle Unfold?
In 881, the Mercians faced a decisive defeat along the banks of the River Conwy. J. E. Lloyd identifies Rhodri’s son Anarawd, who succeeded him as ruler of Gwynedd, as the one who emerged victorious. Documented: J. E. Lloyd, Dictionary of Welsh Biography, “Anarawd ap Rhodri”
The Annales Cambriae succinctly records this significant event:
The battle of Conwy. Vengeance for Rhodri at God’s hand.
Documented: Annales Cambriae, Conwy entry labelled 880 in the linked translation; battle dated 881 by J. E. Lloyd
This brief entry does not mention the names of the commanders or specify the opposing forces. Nevertheless, it clearly links the battle to the theme of vengeance for Rhodri.

It is likely that the Mercian army was commanded by Æthelred, Lord of the Mercians. A subsequent Welsh genealogical account refers to the commander as “Edryd Long-Hair”, who is commonly associated with Æthelred. Inferred
What Were the Aftermath and Consequences?
The victory at Conwy did not signify the end of Anarawd’s interactions with external powers. Asser, in his Life of King Alfred written in 893, recounts how Anarawd and an unnamed brother severed their ties with the Northumbrians to seek support from Alfred. Asser notes that their previous alliance with the Northumbrians had brought Anarawd “no good but harm”. Documented: Asser, Life of King Alfred, chapter 80
Alfred received Anarawd with honour, offering him gifts and acting as his sponsor during his confirmation. Asser indicates that Anarawd then pledged allegiance to Alfred along with all of his people, under similar terms as those agreed by Æthelred and the Mercians.
